OIL-CUP FOR SHAFT=BEAR|NGS.

SPECIFICATION forming part of Letters Patent No. 694,605, dated March4, 1902.

Application filed May 1, 1901. Serial No. 58|Z85. (No model.)

To on whom it may concern:

Be it known that I, FRANK E. BoooRsnLsKI, a citizen of the United States of America, residing at Springfield, in the county of Hampden and State of Massachusetts, haveinvented certain new and useful Improvements in Oil-Cups for Shaft-Bearings, of which the following is a description, reference being bad to the accompanying drawings, wherein Figurelis a perspective view of an oil-cup embodying said improvement. Fig. 2 is a View of the same in central vertical section. Fig. 3 is a View of the same in horizontal sec; tion on the plane 00. Fig. 4. is a perspective View of the interiorly-contained cylinder. Fig. 5 is a view of the oil-cup attached to a bearing, the latter in vertical cross-section..

The object of the improvement is the production of what is generally known as an oil-cup for shaft-bearings, having features of novelty and advantage.

In the accompanying drawings the letter a denotes a bearing or the like, which contains a shaft-bearing which needs to be oiled.

The letter Z) denotes a cup, which preferably is made of sheet-brass and drawn into shape after the fashion used in making metallic cartridge-shells. Of course it may be bored from solid metal or made in any other suitable way. This cup contains in its side. a Valve-orifice b.

The letter 0 denotes a cylinder contained within the cup I). It is made of thin elastic sheet metal, preferably brass. For making this a blank of. the shape shown in Fig. 4 may be used. In and from that blank the cupshaped valve 0 is out, the valve being integral with the plate. Then the blank is sprung into a cylinder, the edges of which may or may not quite meet. Now the cylinder 0 is pushed into the cup 1) until the valve 0 is coincident with the valve-orifice b, as seen in Fig. 2. The elasticity of the interior cylinder holds it firmly in contact with the interior Wall of the cup, and the cup-shaped valve sitting into the valve-orifice holds the two in correct relation to each other rotaril y. The cylinder projects from below the cup I), and by means of its elastic quality it can be sprung into the -oilhole in the bearing and be there retained with sufficient firmness.

In filling the device one has but to push back the cup-shaped valve 0 with the tip or point of an ordinary oil-can.

I claim as my improvementl. The stationary cylinder having a valve formed integrally therewith by punching from sheet metal, in combination with the cup adapted to fit over said cylinder having a valve-orifice coacting with said valve, substantially as described and for the purposes set forth.

2. The cup with a valve-orifice in its side, in combination with the cylinder open at both ends and contained therein and having a yieldingly-supported cup-shaped valve projecting beyond the outer surface of the cylinder and in engagement with said valve-orifice, substantially as described and for the purposes set forth.

3. In combination in an oil-cup the stationary split cylinder open at both ends and having a valve formed integrally therewith and a cup fitting over said cylinder and having a valve-orifice closed by said valve, all substantially as described and for the purposes set forth.

4.. In combination in an oil-cup the stationary interior cylinder open at both ends and having a yieldingly-supported cup-shaped valve formed integrally therewith and a cup having a valve-orifice in its side in engagement with said yieldingly-supported valve,

all substantially as described.
